摘　　要：利用流域汇流单位线进行短期洪水预报是目前普遍采用的技术手段。根据实际工作需要,提出了利用Excel软件的线性规划功能来推求流域汇流单位线,该方法对比其它推求单位线的方法具有理论基础强、使用简便、速度快、精度高等优点。以Excel软件实际操作界面为例,对实例流域的一次洪水过程进行了单位线分析解算,成果完全满足相关精度要求,最后对分析流域汇流单位线应注意的事项和具体问题的处理方法提出了合理化建议。The confluence unit hydrograph in a watershed is widely applied to forecast short-term flood in present.According to the actual need in work,a method,in which watershed confluence unit hydrograph is estimated by using linear planning function of Excel software,is put forward.Compared with other methods,it has many advantages,such as reliable theoretic support,simple operation,and accurate estimation.Taking actual operation interface of Excel software as an example,the unit hydrograph of a real flood process in a watershed is estimated,the results meet the requirements of accuracy.Finally,some attentions that must be paid to the method and reasonable suggestions are put forward.
